EXTENSION-TRUNK FOR STRAW-STACK'ERS.

SPECIFICATION forming part of Letters Patent No. 548,758, dated October '29, 1895.

A plication filed June 14,1894. Serial No. 514,590. (No model.)

To all whom it may concern.-

Be it known that I, NICHOLAS LAUTERBACH,

a citizen of the United States, residing at Meriden, in the county of La Salle and State of Illinois, have invented. a new and useful Extension-Trunk forStraw-Stackers, of which the following is a specification.

My invention relates to straw-stackers, and particularly to those machines adapted for stacking straw and other grain during windy weather, the objects in view being to provide means whereby the trunk may be extended as' the stack increases in height, to insure the depositing of the straw accurately upon the top of the stack, and to avoid leaning caused by irregular formation of the stack.-

Further objects and advantages of the invention will appear in the following descripwill be particularly pointed out in the appended claim.

In the drawings, Figure l is a sectional view of a stacker having a trunk constructed in accordance with my invention. Fig. 2 is a plan view of the same. Fig. 3 is a view of a modified form of the stacker-trunk in which the movable section of the stacker telescopes within the main section thereof. Fig. 4 is a similar view of another form of the stackertrnnk in which the movable section is arranged to fit within the main section and between the same and a guard carried by the main section. Fig.5 is a similar view of another modified form of the stacker-trunk in which an intermediate telescoping section is employed.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 is a partial diagrammatic representation of a thrasher to which the stacker is attached, and 2 represents a guide forming a part of the stacker and communicating with one end of the trunk 3. This trunk comprises a main section 4, which is pivoted at its inner end and lower side to the guide 2 and is adapted at its upper side to slide over the rounded or arc-shaped upper side ofsaid guide, and one or more telescoping sections 5, which are adapted to be adjusted to vary the length of p the trunk.

In Fig. 1 a single adjustable section 5 is litted over and receives the outer end of the main section 4, and slidably mounted upon the main section is a rack 6, connected, by means of a rod 7, with the adjustable section. Meshing with this rack is a pinion 8; carried by a transverse shaft 9, to which is attached a hand-wheel 10 in convenient position for manipulation by the operator. Pivotally connected to the outer end of the adjustable section is a hood ll, ich is connected by means of an operating-rod T2 with a hand-lever 13, mounted upon the rack 6, in operative relation with a notched segment 14, formed-in the inner end of the rack, whereby the hood may be raised or lowered, as desired, and it will therefore be seen that the lever 13 and the segment 14 form an adjusting mechanism for ;the hood.

In connection with the above-described construction is the derriok 15, having a cable 16, attached to a bracket 17 on the outer end of the'main section and reeled upon a drum 18, whereby the trunk may be elevated or lowered as the work proceeds.

In the form of my invention which is illustrated in Fig. 3 the construction is identical, with the exception that the outer or adjustable section is fitted within the main section, and in the modified form shown in Fig.4 the outer or adjustable section is fitted within the main section, as in Fig. 3, and attached to the main section is a tubular guard 19, which covers the inner end of the outer or adjustable section and forms a shield.

In the modified form shown in Fig. 5 aplurality of outer or adjustable sections is provided, the terminal section 21 being fitted over the outer end of an intermediate section 22, which in turn is fitted over the outer end of the main section 4, and the means for operating said adjustable sections are the same as those described in connection with the form of my invention shown in Fig. 1, the rod 7, which extends from the rack 6, being attached to the terminal section 21.

From the above description it will be seen that/as the stack increases in height and the derrick or lifting device is operated to elevate the outer end of the trunk said trunk may be extended by turning the hand-wheel 10 to adjust the discharge-hood 11 properly over the center of the stack, and thus maintain a regular and properly-balanced stack. Furthermore, the arrangement of the lever foradjusting the hood upon the raclgbywhich the adjustable section of the trunkis extended or retracted, places the means for operating all parts of the device Within reach of an operator stationed at the inner end of the trunk, and, as the rack moves With the adjustable section, the connection between the hood and the lever remains permanently at the same tension. Furthermore, it Will be understood that in practice various changes in the form, proportion, and the minor details of construe tion may be resorted to Without departing from the spirit of the invention or sacrificing any of the advantages thereof.

Having described my invention, what I claim is- In a pneumatic straw stacker, the combination of the main tubular trunk section, an adjustable trunk section fitted to the main section and provided at its outer end with an adjustable hood, a rack provided atone end With a rod extension attached to the adjustable trunk section and at its opposite end with an adjusting mechanism, a suitably arranged pinion meshingwith the rack to adjust the same, and a connection between said adjusting mechanism and the adjustable hood of the adjustable trunk section, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two Witnesses.
